I use Lightwave 5.6, have 6 (but not installed until my own computer is repaired) and I do all of my modelling in it. Go on over to the SciFi-Art web pages and forums to truly see a diversity in how the various programs can render. The majority of the professional 3D studios, like Foundation Imaging, use Lightwave. As Peter (PJF) says, jump on the opportunity to get LW 6 while you can at that price.
